Letters Patent No. 99,769, dated February 15, 1870.

IMPROVEMENT IN GAS CARBU'RETING- APPARATUS.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, JOHN GAIR, of the city and State of New York, have invented. an Improvement; in Gas-Oarbureting Apparatus, and the following is declared to be a correct description of the same.

This invention relates to that class of gas carbureters in which heated hydro-carbon vapors emerge from a'small nozzle,.and carry with them a sufiicient quantity of air to make the proper admixture in the pipes for burning without smoke.

My invention relates to the use of a vaporizing tube, containing sand or similar porous material, combined with a reservoir containing the liquid hydro-carbon and an injecting nozzle, the parts being arranged insuch a manner that the vapor consumed in keeping the appa ratus warm is derived from the liquid hydro-carbon inthe same manner as the other lights, or by an apparatus that is used to evolve suflicient gas to light the ggencratin g burner.

In the drawinga is a reservoir to contain gasoline or other liquid hydro-carbon, the same being of any desired size or construction.

b is a tube', leading from the bottom of said reservoir to the valve c,'that regulates the supply of hydrocarbon vapors to the injector nozzle d.

c c are openings that admit air, and f is the pipe the holder f will not escape except through the tube- 9 and the burner. By this means the burner can be started by the action of the mouth, and avoid the separate heating devices heretofore made useof.

After the apparatus has become warmed up, the cock t may be closed and the cock 7; opened, seasto take the gas from the pipe f,- the holder-f will, how ever, still continue to contain gas and act to equalize the pressure, and will supply the gas to the burner whenever it may be started after having been extinguished.

I prefer to make use of a valve, 3, in the burner 7:, as shown in the enlarged section, fig. 2, said valve preventing the gas flowing too rapidly to said burner, as said valve will rise and partially close the exit to the burner when the pressure becomes too great.

I claim, as my invention 1. The tube containing a porous packing, through which the tube '5 passes, in combination with the burner h and nozzle (7, substantially as set forth.

2. The gas-holder f, in combination with the blowtube m, reservoir (1, burner 71., and packed tube b, as and for the purposes set forth.

Dated December 15, 1869.
